BOLT AND FASTENER THEREFOR.

SPECIFICATION forming part of Letters Patent No. 708,486, datedSeptember 2, 1902.

Application filed May 20, 1902. Serial No. 103,227. (No model.)

To all whom, it may concern:

Beit known that I, ALBERT H. LEWIS, a citizen of the United States,residing at Uhrichsville, in the county of Tuscarawas and State of Ohio,have invented new and useful Improvements in Bolts and FastenersTherefor, of which the following is a specification.

My invention relates to improvements in bolts and means for fasteningthe same in position; and it consists in a certain peculiar andadvantageous bolt and bolt-fastener designed. more especially for use inrailway-rail joints, as will be hereinafter fullydescribed and claimed.

In the accompanying drawings, Figure 1 is a side elevation of arail-joint embodying my improvements; Fig. 2, an enlarged transversesection taken in the plane indicated by the broken line 2 2 of Fig. 1and showing the improved bolt in elevation; Fig. 3, an enlargedperspective View of the improved bolt removed, and Fig. 4 a similar viewof the boltfastener.

Similar letters of reference designate corre- 2 5 sponding parts in allof the several views of the drawings, referring to which A A are themeeting ends of two railwayrails, which are preferably provided in theirwebs with the usual oblong apertures a, to

0 permit of expansion and contraction; B, a fishplate or splice-bardisposed at one side of the rails and having apertures b coincident withthe apertures (1 thereof; 0, a splice-bar or fish-plate disposed at theopposite side of the rails with reference to plate B and extending bypreference up at the side of the rail-heads to points flush with thetreads thereof and provided with transverse apertures c coincident withthe apertures a; D D,

bolts constructed in accordance with my invention and extending throughthe registered apertures of the fish-plates and rails, and E Ebolt-fasteners, also constructed in accordance with my invention. Thebolts D are similar in construction, and therefore adetailed'description of the one shown in Figs. 2 and 3 will suffice toimpart an understanding of all. Said bolt is provided at one end withthe usual head d, and adjacent to said head it has a lug e, designed toseat in a complementary offset of the aperture Z), with a view ofholding the bolt against turning on its axis. Adjacent to its oppositeend and in its upper side the bolt is provided with a crosswise kerf orgroove f, the outer wall g and bottom wall h of which are by preferenceslightly undercut and inclined downwardly and inwardly, respectively, asshown.

All of the bolt-fasteners E are similar in construction to and areapplied in the same manner as the fastener E shown in Figs. 2 and l.Said fastener E is formed of one piece of suitable metal and has sidewalls 1', joined by an outer end wallj and preferably by a top wall 70.The said side walls t" have convex serrated 0r toothed inner ends Z, andthe top wall 7t when employed also has a serrated inner end Z, designedto engage the plate 0, while the end wall j has a pointed toe m, adaptedto enter the groove f of the bolt D and bear against the wall orabutment g after the manner shown in Fig. 2.

In applying the improvements the bolt D is placed in registeredapertures of the fishplat-es and rail, so that it projects aconsiderable distance beyond the plate 0, and the fastener E is arrangedwith its toe m in the groove f of the bolt and its convex serrated endbearing against the plate 0. When the fastener is disposed as stated andits serrated end is pressed downwardly, it will be observed v that thebolt will be drawn tight and securely fixed in position; also, that whentrains pass over the joint the jar will tend to work the serrated end ofthe fastener downwardly and cause it to further tighten or take uplooseness or lost motion of the bolt due to wear. The serrated end ofthe fastener engaging the side of the fish-plate 0 holds the fasteneragainst casual upward movement, and hence o effectually prevents casualloosening of the connection between the rail and fish-plates.

I have shown the joint as embodying four bolts and four fasteners; butit is obvious that any desired number of bolts and fasteners may beemployed in a joint without departing from the scope of my invention. Ialso desire it understood that while designed more particularly for usein rail-joints my improved bolt and fastener may be used in otherconnections to which it is applicable with advantage.

Having described my invention, What I claim, and desire to secure byLetters Patent, 1s

1. A bolt havingacrosswise abutment thereon adjacent to one end, incombination with a fastener adapted to bear at one end against thecrosswise abutment of the bolt, and havin g an opposite convex andserrated or roughened end to engage a device through which the bolt ispassed.

2. A bolthaving a crosswise groove adjacent to one end, the outer wallof which is undercut and constitutes an abutment, in combination with afastener having a toe at its outer end and adapted to bear in thegroove, and also having a convex and serrated or roughened inner endadapted to be pressed into engagement with a device through which thebolt is passed.

3. Abolt havingacrosswise abutment thereon, undercut at its inner side,in combination with a separate fastener having a pointed toe at itsouter end adapted to bear in the undercut of the abutment, and an innerend adapted to engage a device through which the bolt is passed.

4. The combination of a bolt havinga crosswise groove, the outer Wall ofwhich is undercut, and a fastener having the side and top Walls, andalso having the toe at its outer end disposed in the crosswise groove ofthe bolt, and its inner end rounded and roughened or serrated.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.

ALBERT H. LEWIS.
